IMPROVEMENT IN CAR-COUPLINGS.

- Specification forming part of Letters Patent No. 191,850, dated June12, 1877; application filed May 28, 1877.

To all whom it may concern 4 Be it known that I, DAVID R. HALTER, ofLees Cross Roads, in the county of (lumberland and State ofPennsylvanfa, have invented a new and Improved Oar-Coupling. of whichthe following is a specification In the accompanying drawing, Figure 1represents a vertical longitudinal section of my improved ear-coupling;Fig. 2, an end view, partly in section on line :0 m, Fig. 1; and Fig. 3,a vertical transverse section of the same on lfney 3 Fig. 1.

Similar letters of reference sponding parts.

The invention relates to that class of autoindicatecorrematically-working car-couplings by which the entering of thebrakeman between the cars, and the consequent danger to life and limb,are avoided, and cars with platforms of different heights coupled andreadily uncoupled at any time, even when they are in motion.

The invention consists of a draw-head having hinged, springacted. andadjustable coupling-link, in connection with adraw-head having a pivotedand weighted draw-lever and a laterally-sliding coupling and uncouplingpin.

In the drawing, A represents one drawhead, and B the connectingdraw-head, of my improved automatic coupling, which may be arranged inconnection with cars having platforms of difi'erent height.

The draw-head A is provided with a sidewise-pivoted guide-frame, O, atsome distance back of the month, said guide'frame having a centralrecess, to which the sliding stock D of the couplingliuk D is secured bya vertical pin, a, passing through holes of' the guideframe (J and ahole of the stock.

The link-stock D may be provided with several pin-holes at diflerentdistances from each other, so that the link may be adjusted to extendat, greater or less length from the draw-head, and couple the cars atdifferent distances from each other, as desired. The link-stock hascushioning side and bottom springs b, that retain the link in centralposition to facilitate coupling.

The link is firmly attached to side grooves of the stock byafastening-band, 01, extending around the link and front end of stockThe link enters the opposite draw-head B and passes along inclined sideshoulders e of the same, striking against a pivoted and weighteddraw-lever, E, so as to throw the same back until it has passed beyondthe upper part of the same, which is then. carried up again by its lowerweighted arm, soas to couple the link.

A cross-pin, F, extends laterally back of the lower weighted arm of thecoupling-lever E, and prevents the forward swinging of the same and theuncoupling of the link. The cross-pin may, however, be withdrawn by apivot link and lever, F, attached to the outside of the draw-head, thecross pin sliding in suitable guides at the bottom of the drawhead. Assoon as the cross-pin is withdrawn the coupling-lever swings forwardandadmits the uncoupling of the link. This may be accomplished at anytime, even when the cars are in motion, while also both draw-heads mayreadily be coupled, respectively, with the common pin and link.

Having thus described my invention, I claim as new and desire to secureby Letters Patent l. The combination of draw-head A, having swinging andspring-acted coupling-link, with the drawhead B, having pivoted andweighted draw-lever E and laterally-sliding coupling and uncoupling pinF, substantially in the manner and for the purposes set forth.

2. The combination of draw-head A, having pivoted guide-frame G, withthe adjustable lin k-stock, having cushioned side and bottom springs,and with the locking-pin a, passing through guide-frame and stock,substantially as specified.

3. The combination of link-stock D, having side grooves, with theforward extending coupling-link D and fastening-band d, substantially asdescribed.
